i hate those ansers
To find the first number, we need to set up an equation based on the given information and then solve for the unknown value.
Let's call the first number "x". According to the problem, when you add x to another number four times as big, the result is 30.
Expressing this information in the form of an equation, we have:
x + 4x = 30
Combining the like terms, we simplify the equation:
5x = 30
Now, we can solve for x by isolating it on one side of the equation:
Divide both sides by 5 to get:
x = 30/5
Simplifying further, we get:
x = 6
Therefore, the first number is 6.
